Jenneria Pustulata
''Jenneria pustulata'', common name the Jenner's cowry or pustulated cowry, is a species of small sea snail, a marine gastropod mollusk in the family (biology), family Ovulidae, one of the families of cowry allies. Description The shells of this common species reach on average in length. The shape is usual spindle-like or oval. The dorsum surface is decorated with numerous brilliant orange-red bumps or pustules (hence the Latin name ''pustulata'') surrounded by a dark ring. The basic color of the dorsal surface is grey, beige or brown. The fine labial teeth are prominent, their color is white or pale brown, and they cross the entire base, with dark brown spaces in between. In the living animals the mantle is greyish, with long tree-shaped sensorial papillae. Distribution This species occurs in California, the Gulf of California in Western Mexico, Nicaragua, West Panama, Ecuador, Peru Costa Rica and the Galapagos. Habitat These sea snails live in tropical to temperate waters at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Panama
Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half the country's million people. Panama was inhabited by indigenous tribes before Spanish colonists arrived in the 16th century. It broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Canal to be completed by the United States Army Corps of En ...

Pediculariidae - Jenneria Pustulata-3
Pediculariinae is a subfamily of small to large predatory or parasitic sea snails, marine gastropod molluscs in the family Ovulidae and the superfamily Cypraeoidea, the cowries and the cowry allies. As of 2009, it comprises 48 described species of which 20 are regarded as valid by most scientists. Taxonomy Simone (2004)Simone L. R. L. (2004). "Morphology and Phylogeny of the Cypraeoidea (Mollusca, Caenogastropoda)". ''Papel Virtual Editoria'' (Rio de Janeiro): 185 pp. placed some genera in the family Pediculariidae which were previously in the family Ovulidae. Comparison of the shell, radula and morphology suggested a closer phylogenetic relationship to the Pediculariidae than to the Lamellariidae, the Eratoidae/Triviidae, or the Ovulidae. However, both the validity of the family Pediculariidae, and its proper position within the superfamily Cypraeoidea, remain controversial. As of 2019, the World Register of Marine Species considers it a subfamily of the family Ovulidae. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scleractinia
Scleractinia, also called stony corals or hard corals, are marine animals in the phylum Cnidaria that build themselves a hard skeleton. The individual animals are known as polyp (zoology), polyps and have a cylindrical body crowned by an oral disc in which a mouth is fringed with tentacles. Although some species are solitary, most are Colony (biology), colonial. The founding polyp settles and starts to secrete calcium carbonate to protect its soft body. Solitary corals can be as much as across but in colonial species the polyps are usually only a few millimetres in diameter. These polyps reproduce asexually by budding, but remain attached to each other, forming a multi-polyp colony of cloning, clones with a common skeleton, which may be up to several metres in diameter or height according to species. The shape and appearance of each coral colony depends not only on the species, but also on its location, depth, the amount of water movement and other factors. Many shallow-water co ...

Pocillopora
''Pocillopora'' is a genus of stony corals in the family Pocilloporidae occurring in the Pacific and Indian Oceans.Veron, J.E.N. (2000) Corals of the World. Australian Institute of Marine Science, Townville, Australia. They are commonly called cauliflower corals and brush corals. Description Cauliflower corals are widespread and can be identified by the presence of wart-like growths on their surface. The colonies can be dome shaped or branching and are very variable in colour and shape depending on the species and the environmental conditions. Species situated on shallow reefs pounded by the sea tend to be stunted whilst those in deep calm water are often thin and open. Each individual polyp has tentacles but these are normally extended only at night. Biology The polyps are hermaphrodite, possessing four sets of male and four sets of female gonads. Pocillopora can reproduce asexually via fragmentation. They also reproduce sexually and the larvae develop inside the polyps rather ...

Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
